tasks performed by a miner

Question

Dear MC team,

could you clarify a detailed list of the steps perfomed by a miner node (in round robin mode, not bitcoin-like pow). I guess something like:

- check that the block is signed in a proper way
- check the consistency of the transaction in the block with the miner blockchain
- sign the block before broadcasting

Thanks for you support.

Answer 1

The miner checks that every transaction in the block is valid and does not conflict with other transactions in the block or in previous blocks in the current chain. (These checks are actually performed when each transaction arrives, not at the moment of block creation.) The transactions are put together in the block with the miner's signature and then the block is broadcast. More on miner signatures here:
